Application filed May 25,

:This invention relates to woodworking machines and particularly tomachines rendered'convertible to adapt them to use for various machiningoperations. 7

It :is the object of the invention .to provide a machine ofthischaracter in which the power transmitting means comprising a drivingmotor and a driven mandrel are. combined in a unitary mounting pivotallysupported upon the frame of the machine and connected with controllingmeans by which said mounting maybe tiltedbodily .to establish saidmandrel in angular driven positions relative to said frame, a furtherprovision being made for effecting adjustment of the mandrellongitudinally upon the mounting in .a certain established posi- .tionof the latter. 7 V n A preferred embodiment of the invention I is[illustrated in the accompanying drawings, wherein,' Fig. 1 is an endelevation of the machine.

Fig. 2 is a side elevation showing the .parts .as in the position ofFig. 1.; in which the mandrel is in a horizontal plane for use .as a sawarbor or the like.

' Fig. 3fis also a :side elevation showing the power transmitting unittilted with the mandrel in a vertical position to serve as the spindleof a shaper.

In these views the reference character 1 designates the legs of a frameconnected uponopposite sides by upper and. lower transverse rails '2 and.3 respectively, cross rails 4 at opposite ends and an intermediatecross rail 5 connecting thelower side rails 3 the parts being preferablyformed integral. Journal bearing boxes 6 are secured by bolts 7 upon theside rails .2 intermediate the ends of the frame and mounted upontrunnions .8 journaled in said bearings is a platform 9 adapted to tiltor rock thereon through a range of 90 degrees, movement being impartedto tilt and to some extent retain said platform in angular positions ofadjustment by "means of a worm wheel 10 fixed upon a trunnion 8 andmeshing with a-worm shaft 11 journaled in .a bearing bracket 12 securedby bolts 13 to a side rail 2. of the frame, said worm shaft having a1923.

hand wheel 14. by which a may be rotated.

, An electric motor '15 havinga pulley 16 is secured at its base bybolts 17 to the under face of the platform 9 to swing in unisontherewith, and extending concentric 55 with the "pivotal axis of saidplatform in spaced relation to the under face of said motor is anareuate brace 18 engaged 'at its upper end with a leg 1 and secured at.its lower end by bolts 19 With'the rail 50f the frame. Said brace has aradial slot '20 receiving the stem of aboss 21 bolted to the motor andhaving screwfthreaded engagement withv a hand Wheel '22 by means ofwhich said motor may be clamped to said brace in any tilted position ofthe platform.

Formed in the upper -face of said platform is a transverse way or groove23' hav ing undercut edges for the reception .of the correspondinglyshaped base 24 of -a yoke shaped journal bracket 25 adapted to slidelongitudinally therein. Movement of said bracketiscontrolled by a screwshaft 26 journaled at opposite ends in bearings .27 integral with saidplatform and having screw threaded engagement intermediate said.bearings with a lug 28 projecting laterally from the bracket 25. Saidshaft is held againstaxial movement in its bearings by collars 29 andhas fixed upon one end thereof a beveled gear 30 adapted to mesh with abeveled gear 31' in the tilted position of the platform as-shown in Fig.3. Thegear 31 is mounted upon a horizontal shaft 32 which is journaledat one end in a bearing extension 33 on the rails .2 of the frame and atits opposite end said shaft is ,journaled in a bearing 34 on a leg 1 ofthe frame and carries .a hand wheel 35 by which it may be rotated totransmit rotation to the screw 26 and impart movement to the bracket 25longitudinally thereof.

The extremities of the bracket .25 are pro vided with bearing boxes 36in which a shaft 37 is .journaled adjacent its ends and which 5 isretained against axial movement by thrust collars 38 engaging saidbearings. One end 39 of said shaft projects beyond saidbracket and isadapted to serve as a saw arbor in' the horizontal position as 00 and asa shaper OSIt IOD of Fig. 3, i the re engaged at its upper end with astationary table l-l mounted on said frame. Said brace has a transverseslot 4-5 concentric with the axis of the platform 9, terminating in avertical extension 4:6 at the lower end thereof, and extending throughsaid slot from a lateral boss 1-? on the bracket 25 is a screw threadedstem 48 engaged by a hand wheel 49 by which saidbracket may be clampedto said brace in tilted positions of said platform, the vertical slot 46bein adapted to accommodate axial adjustment of the shaft 3? in thevertical position of thebracket, as in Fig. 3.

Supported upon laterally extending inclined brackets 50, integral withthe bear ings 6, are like sections 51 of a centrally divided table thesections of which are similarly mounted upon adjustable wedges 52engaged by the screws of hand wheels 58 journaled in said brackets andby means of which said sections may be adjusted "elative to the cutterhead 40.

' A tiltable table 54: is supported above the spindle 39 upon spacedrocker brackets 55 ngaged with the upper ends of the legs 1, each havingan arcuate slot 56 receiving a stud 57 anchored in the leg andscrewthrcaded engagement ith a hand wheel 58 for clamping said bracketsto said legs. T he periphery of one of said brackets is formed with wormgear teeth 59 in mesh with a worm shaft 60 journa -led in a leg 1 andhaving a hand wheel 61 for rotating said shaft to impart a rockingmovementto said brackets and effect a tilting of said table.

it will now be understood that with the parts in the position of Figs. 1and 2 the driven shaft 37 is so disposed as to enable the cutter head 40to be used in connection with the table sections 51 for planing andjointing purposes, while the spindle 39 may be employed with thetiltable table 54L for various sawing operations. By releasing thehand'wheels 22 and d9 from binding enent with their respective bracesand havingsegarated the table sections 51 and tilted the table 54;sufficiently to provide clearance for passage of the spindle 39, thehand wheel 14 may be rotated to turn the gear and swing the platform 9with the of said support.

motor and driven shaft 37 to the vertical position of Fig. 3. In thisposition the gear will mesh with the gear 31, and the stem d8 of thebracket 25 will have passed into the slot 46 of the brace 43, so thatupon rotating the hand wheel motion will be transmitted through saidgears to turn the wormshaft 26 through which movement will be impartedto vertically adjust the bracket 25 and establish the shaft 37 in thedesired axial relation to the table l4 to enable the spindle 39 whoemployed for shaping operations. 7
